Smoke and Heat Exhaust Control Unit mcr 9705
– User Instruction Manual
Strona 3 z 24
1. Introduction
The mcr 9705 control unit is used in smoke exhaust systems to control the operation
of:
- electrical actuators and in particular vent actuators in mcr PROLIGHT,
mcr THERMOLIGHT, mcr ULTRA THERM, mcr LAM, mcr LAM-N,
-
valves of alarm boxes with CO2 cartridges,
- drive of automatic rolled curtains PROSMOKE CE/CE1, mcr
PROSMOKE FSv2 CE,
- electromagnetic door locks and in other mcr series products used for fire
protection purposes, which require 24 V= power supply.
The electrical mcr 9705 unit should be installed near the smoke exhaust
window or in the building supervision room. The unit is powered with 230 V AC
voltage. The working DC voltage is 24 V on output terminals to which the devices of
the electrical smoke exhaust control system are connected. The unit is equipped with
batteries which ensure system operation for 72 hours after a power outage. After that
time a single emergency opening of smoke vents is possible.
If the mcr 9705 control
panel is used to control the PROSMOKE FSv2 CE mcr curtains, the standby time
depends on the number of connected curtains (for details refer to the mcr
PROSMOKE FSv2 CE curtains).
The unit has the following features:
•
automatic alarm release by a signal from a fire alarm control unit
•
manual alarm release by alarm pushbuttons,
•
automatic alarm release by smoke sensors,
•
transmitting information about alarm (NO/NC signal),
•
transmitting information about the defect of the system (NO/NC signal),
•
transmitting information about vent opening (NO/NC signal),
•
manual opening of a smoke vents for ventilation of the building during
normal operation without activating the alarm status,
•
automatic closing of smoke vents opened for ventilation, in case of rain or
strong wind (when a weather monitoring unit with a wind-rain sensor is
installed).
The mcr 9705 unit is equipped with audio and visual alarm indicators of its
operating status, which allows easy identification of the alarm’s source or a system
defect.
Smoke exhaust vents which were opened in emergency mode can be closed
(cancellation of the alarm state) providing that the cause of the alarm has been
removed. If mcr 9705 is equipped with manual pushbutton mcr RPO-1, remote
operation and display of the unit’s status is possible (defect and alarm signals,
remote alarm reset and closing vents after the alarm).
mcr 9705 is performed in two series of type, which are based on modules:
- 5 A, 2 x 5 A, 3 x 5 A, 4 x 5 A, 5 x 5 A, 6 x 5 A, 7 x 5 A, 8 x 5 A;
or
- 8 A, 2 x 8 A, 3 x 8 A, 4 x 8 A, 5 x 8 A, 6 x 8 A, 7 x 8 A, 8 x 8 A.
Series of type [8A] shall be used only for natural smoke and heat exhaust systems.
